MACHINEFOR FINISHING TONGUES.

SPECIFICATION forming part of Letters Patent No. 702,671, dated June 17, 1902.

Application filed March 23, 1900. $erial No. 9,900 (No model.)

Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in-Machines for Finishing,

Tongues and Similar Purposes, of which the following is a-full description, reference being had to the accompanying drawings,in WhlCll-u Figure 1 is a plan view; Fig. 2, a side elevation; Fig. 3, a side elevation of the machine in section; Fig. 4, a front view; and Figs. .5, 6, 7, 8, 9, 10, and 11 are details.

The object of the machine of my invention is to finish Vehicle-tongues after they have been sawed from the plank. I In manufacturing tongues it is customary to dress all sides of a plank of proper thickness and wide enough to make two tongues in the ordinary planing-machine and then saw diagonally, so as to give each the proper taper. So prepared they are then passed through my machine,which finishes the sawed sides and corners or rounds the four. corners or a part of them, as well as the other side, as maybe desired.

- The principle of the machine will bestbe understood by first referring to Fig. 3,'in. Itis made of two counterparts joined by the stay which A is the main supporting-frame.

rods a a a and a. a forms a portion of the bed over which the tongues move while being operated upon. It is secured to the side frame-pieces A by the bolts a which pass through a slot in downward-reachingezo tensions at each end. Secured, as it is, by bolting through slots, it may be raised or lowered to adjust it to proper height. Upon this,

as shown, is the roller a its surface being slightly above the upper surface of 03. Upon.

the support a are the adjustable guides a between which the tongue to be operated upou head F is upon a shaft journaled in the arm passes.

B is a' feed roller adapted to move the tongue over the planing-head'B.

b and b are guides similar to those a and a their purpose being merely to hold the tongue in proper position. It is thus seen that the tongue is only supported when first entered on the roller 0/ and the feedingroller B.

C is a presser or roller supported upon the arms 0 0. These arms pass downwardly one upon each side of the space provided for the tongue to pass and are connected to the piston-rod c, which passes upward from the compressed-air cylinder 0. The air-cylinders are connected to a main reservoir by the pipe D.

The admission of compressed air into the cylinder is controlled by a tripping device made operable. by the material to be acted upon and has the effect of moving the roller 0 downward, so as to press upon the tongue. It is found best to give the roller 0 its pressure by means of the air-cylinder, for the reason that whatever the taper of the tongue the roller can follow it and substantially the same pressure be maintained, which would not be the case if moved by a spring. In its normal position the roller is elevated,as shown in Fig. 3.

Upon a rock-shaft E is the arm e of the tripping device, and extending from it horizontally is the arm c.

c is a three-way air-valve, which is connected by the rod 0 to the arm e. Upon passing the tongue into the machine it engages the arm 6 on the rock-shaftEand moves it downward, thus opening the valve 0 and admitting air into the cylinder O,which forces the roller 0 downward. Thus introduced the tongue is firmly held and by the operation of the feeding-wheel B is moved over the planer-head B.

F and F are chamfering cutter-heads, one

above and the other below the tongue-passage. The bottom surface of the tongue moves upon a horizontal plane, and the chamfering-head F is so supported that it. may

[move downward with the taper of the tongue as the latter passes through the machine. It is also essential that the chamfering-head F. rise at the proper time while the tongue is passing through. Both these are accomplished in the following manner: The cutterjournaled in the main frame, are the vertical rollers H and H, placed upon each side of the path of travel of the tongue. These shafts are j ournaled belowin the bearings hh,which are bolted to the crossbar h by bolts passing through slots in a cross portion of the main frame. By means of these bolts and slots the journal-bearings may be adjusted from each other and held there. Near the top of the frame are the bearings 7L2 71 supported in the cross-bar of the frame 72.3. The journal-bearings are provided with a collar above this bar and with a nut it below. This provides for adjustment of the upper ends of the shafts, so that the rollers II may be placed a proper distance apart so as to engage the tongue with sufficient pressure to draw it through the machine after its last end has passed the feeding-roller B. These two shafts last mentioned are geared together, as shown in Fig. l, by the gears 7L5 7L5. Upon the shaft is also the worm-wheel 7L6, and journaled in the main frame is a worm-shaft 7L7. Upon this latter shaft is the pulley 72.

The above-mentioned rotary parts,to which power is imparted, are given motion in the following manner: Suitablysupported above the machine may be placed counter-shafts over which the belts 1, 2, and 3 are supposed to be thrown. The belt 1 passes around the pulley I on the cutter-head shaft and gives the latter rotation in the proper direction. The belt 2 passes around the pulley J upon the shaft J. Upon the shaft J is also the pulleyj. Over the pulleyj and over the pulley f on the shaft f the belt j is thrown. By means of this the chamfering-head F is given rotation. Upon the shaft J is also the pulley J and upon the shaft K, suitably journaled on the frame, is the pulley K. Over the pulleys K J is thrown a half-twist belt 70. The shaft K is thus given rotation, and through it the feeding devices move. Upon the shaft K is the sprocket-wheel 7t, and upon the shaft L is the sprocket-wheel Z, to which the feeding-wheel B is secured. Over the two sprocket wheels a chain is thrown, and thus movement imparted to the feeding device B, first to act upon the tongue. Upon the shaft K is a pulley W, and around it and the pulley its is thrown a belt 7L By this means movement is imparted to the feeding-rollers H 1-1, last to act upon the tongue. Upon the shaft G is also the driving-pulley G which takes the belt 3. The pulley G is upon the shaft G. Upon the arm fis placed the pulleyf Around the latter two the belt f is thrown.

-Referring now to Fig. 9, the mechanism for moving the chamfering-head-supporting arms ff will be best understood. N is a rockshaft passing from one side to the other of the frame of the machine and suitably journaled therein. N is also a rock-shaft passing from one side to the other of the machine and suitably journaled in the main frame. Upon the rock-shaft N is the cam 71, upon which an antifriction-roller n on the end of the arm f rests. n is a downwardly-reaching arm suitably secured to the shaft N, into an eye in which the spring is hooked. The said spring is also connected to the cross-bar a of the main frame.

P is an air-cylinder connected by pipes to the main supply-pipe D, the latter being provided with the valve 13. The cylinder is provided with the usual piston and rod. The purpose of the spring 0 is to hold the cam in the position shown in Fig. 3.

The device next to be described may be better understood by reference to Fig. 6, in which the cylinder Pand various pipes, links, and levers are shown; but for clearness the pipes are shown broken, and the cylinder is placed on the same horizontal plane as the pipes. P is a roller upon the arinp, pivoted to asuitable part of the frame at 232. The lever extends beyond the pivot and is connected at p to the link p. This link is connected at p to the arm 19 of the valve 1). Normally the roller 19 is in the position shown in full lines in Fig. 6; but if the butt of the tongue comes against it, it, the lever, the links, and the three-way valve-leverp are moved to the positions shown by dotted lines. The eifect of this is to open the three-way valve 19 and permit exhaust of the air in the cylinder I. This leaves the piston at the lower end of the cylinder. The purpose of the cylinder P and its piston and rod, let it be understood, is to move the chamfering-heads to and from each other as required, as will now be explained.

The tongues to be chamfered in this machine are by the processes of working them out of the plank planed upon what will be three sides. They are then fed into this machine butt first from the right hand as the machine is seen in Fig. 3. As theyare passed inward the butt strikes the arm 0 of the trip ping device, and through the connection 6 the three-way valve 0 is so moved as to admit air into the top of the cylinder C. Through the piston-rod and the upreaching arms 0 c the roller 0 is broughtdown upon the tongue, and the feeding-wheel passes the latter along over the planer-head B. The butt of the tongue striking the roller 13 causes the three- Way valve 1) to open and permit the airin the upper end of the cylinder to exhaust. The tongue then passes onward, its remaining rough side being dressed in the meantime, until it engages the roller R. (See Figs. 3 and (3.) The tongue that the machine as shown is adapted to work is left unchamfered for some distance from its butt-end, and the roller R is the same distance from the chamfering-heads as that from the butt of the tongue to the point where the chamfer is intended to begin.

S is a two-way valve and has an arm or tip 3 adapted to open and close the same. 8 is a spring connected to the said arm and to the main frame in such a manner as to bring the levers and links connected thereto to the position shown in full lines.

8 is an arm adjustably connected to the main frame and to the arm 5' by the link 5 When the butt of the tongue reaches the roller R on the arm .9 the parts are moved to the position shown by dottedlines in Fig. 6. In short, the movementof the arm having the roller R to the position shown opens the valve S and permits the compressed air to pass into the cylinder P. The movement of the piston-rod outward actuates thebell-crankT, which is pivoted to the main frame, and by means of the link i the arm f is moved down, and with it the cutter-head F. The same movement of the piston-rod through the in strumentality of the link i rocks the cam n upon its support N, 'and'the arm f, having the antiEriction-roller n thereon, is .moved upward simultaneously with the downward movement of the upper chamfering-head. The proportions given to the cam and its arm and the bell-crank T are such as to move the two ehamfering-heads together at the proper rate. The chamfering-heads F and F are made in two parts in the present instance, as it is not desired to chamfer the tongue to the middle line, and the space between them, F", is taken advantage of and the guide f extended between. This is suitably secured to the arm f by means of a bolt, so as to be adjustable vertically. The arms fand f,'al though, as one piece, are, in fact, of two parts; but this is not essential. The cutters of the chamfering'head F are allowed to extend a little below the lower surface of the guide f. This prevents the said chamfering-head from jumping downward into the material being operated upon. In order to'move the roller 0 upward as soon as the air is permitted to pass from the cylinder 0 through the threeway valve 0 a counterpoise-weightU is used. This weight is upon a lever of the first kind, which has its fulcrum upon a stand to, ex tending from the floor and connected to the piston of the cylinder 0.

V is a roller for sustaining the tongue while passing out of the machine.

If the machine is used for the purpose of chamfering only one side or edge of a tapering part, the upper chalnfering-head may be removed, and if it is desired to chamfer all corners of a piece of timber the lower cutterhead may be fixed-atproper height by any suitable means.

It is plain that this machine might be turned upon its side, and, suitably supported, still operate precisely the same as now except that the weight U would have to be connected to the piston-rod c in such a manner as to move the latter horizontally instead of vertically. When I speak in the claims of locating one cutter above the piece to be operated upon and one below, I must be understood as referring to placing them so as to act in opposition merely. The terms upper and lower will be used only because they correspond with the machine as shown in the drawings.

A smooth-surfaced block would serve an equivalent purpose, except that it would offer more resistance to the passage of the material being operated upon.

From the construction described it is clear that the chamfering cutter-heads can be moved simultaneously into their working position, and bya proper shaping of the cam n the lower cutter-head can be raised to'and held in'any desired or definite position while the upper cutter-head ismovedgradually toward it'during the cutting operation.
